CVE-2026-3881Public exploitNetwork attack vector

Unauthenticated blind SSRF via unvalidated URL parameter

Published Mar 31, 2026 · Updated Mar 31, 2026

Server-side request forgery in Qrolic Technologies Performance Monitor 1.0.6 and earlier allows remote attackers to reach internal services. The public curl_data REST route passes its url query parameter into an outbound request without validating the destination. No authentication is required; the blind response limits direct disclosure, but the server can still be induced to contact loopback or other internal addresses.
